Tag Archives: DNS Servers

Lately I have had a bad and unstable internet connection. I have a Mac and it has been working fine for years. My internet provider is Vodafone-Ziggo.

I tried to find out what was wrong using the AirPortUtility.app on my Mac, and I found something strange : when selecting my wireless WiFi-network, my internet connection is presumed working, but when selecting my wired LAN-network, I get an error message saying there is no internet connection.

If it would have been the other way around, I could think of an explanation… but having wireless internet connection from my router and not LAN-internet just doesn’t make sense…

I’ve tried numerous resets of the Ziggo-modem, of my TimeCapsule and of my Mac. Nothing helps.

Do you have any suggestions on fixing this ?

Answer :

Even though you’ve tried most of the available options already, there is one other thing I would suggest to try :

make sure the UTP/Ethernet/LAN-cable is correctly connected into both your Mac and the ‘local network device’ (be it a TimeCapsule, a router, a modem, a network-switch or a wall-socket)

in the window that opens (“Network”), click on “Ethernet” in the list on the left

in the info that appears on the right, check if it says “Status : Connected”

if it doesn’t, your UTP/Ethernet/LAN-cable isn’t connected properly, so check all network-cables again until it says “Status : Connected”

then, click the Advanced-button

in the window that opens, click on the DNS-tab

in the info that opens, at “DNS Servers:” make sure that you have at least included one of the following DNS Servers : 8.8.8.8 (Google), 8.8.4.4 (Google), 208.67.222.222 (OpenDNS) and/or 208.67.220.220 (OpenDNS)

if none of those DNS Servers are listed yet, add them by clicking on the +/Plus-button bottom-left

then click on the Proxies-tab (of the elongated TCP/IP-button)

in the info that opens, make sure to remove the check-mark at both “Web Proxy (HTTP)” and “Secure Web Proxy (HTTPS)”

in case both were already switched OFF, I would suggest to switch both of them to ON

then leave the rest as is, and click on the OK-button

in the previous window that appears, click the “Apply”

now check the AirPortUtility.app again, and you should see that the internet connection is back up for both the wireless and wired/LAN connection

also check by opening Safari (or another internet browser) and refresh the page by clicking on the circular arrow in the address bar
